ABSTRACT

A drinking apparatus which includes a liquid reservoir having at least one liquid outlet ducted from at least one inlet in the liquid pulled within the reservoir, at least one liquid outlet ducted from at least one inlet outside of said reservoir yet in the vicinity of said first liquid outlet, and means to hold said first liquid outlet relative to said second liquid inlet in such a way as to enable suction applied at said second liquid outlet to induce an unducted liquid flow of liquid ducting from the liquid pulled within the reservoir between said first liquid outlet and said second liquid inlet.

TECHNICAL FIELD

[0001] The present invention relates to a drinking apparatus, and in particular but not solely to a drinking apparatus to be used as a novelty item.

[0002] Many different forms of novelty drinking containers are known. Such, include for example those shown in U.S. Pat. No. 3,879,885, where there is a container which has an inlet and outlet straw. The application of suction at the outlet straw will, when the inlet straw is placed in a cup containing liquid, generate a fountain of liquid within the container.

[0003] In U.S. Pat. No. 4,211,024 there is described a drinking straw which has an expanded mid section to provide a surface on which advertising or the like can be placed. The expanded section is first filled with liquid drawn up from the lower section of the straw, before the liquid advances through the upper section to the mouth of the user.

[0004] Likewise in U.S. Pat. No. 5,361,987, there is shown a drinking straw having an expanded section which is filled with liquid prior to advancing out through the upper section. All this prior art is of straw like apparatus for location with a separate cut or glass or cup of liquid. The novelty effect hat these specification teach is either of filling of a compartment prior to displacement from the apparatus, or a fountain effect of a disbursed flow of liquid. It is therefore an object of the present invention to provide a drinking apparatus which will at least provide the public with a useful choice.

DETAILED DESCRIPTION

[0072] With reference to FIG. 1 the drinking apparatus 1 preferably consists of a liquid reservoir means 2 defining a liquid reservoir 17. The reservoir has at least one liquid outlet referred to as the first liquid outlet(s) 12. This is ducted by ducting 4 from at least one inlet referred to a the first inlet(s) 13 through which the liquid within the reservoir may be pulled. The apparatus also includes a means to hold at least one second liquid outlet(s) 14 relative to said first liquid outlet(s) 12. The means to hold is preferably a chamber defining means and holds the second liquid inlet relative to the first liquid outlet in such a way as to enable suction applied at, on or about said second liquid outlet(s) to induce at least a partially unducted liquid flow of liquid ducting from the liquid pulled within the reservoir.

[0073] Between the second liquid outlet and the first liquid outlet, the flow is, partially unducted. In for example FIG. 4, there is a portion of the flow between second liquid outlet and the first liquid outlet which is ducted by a ducting or conduit 6, In FIG. 12 however, there is not such upper ducting provided to the second liquid outlet.

[0074] In the most preferred form the chamber and the reservoir means are substantially of a corresponding external shape for example of a circular shape so that the appearance of the product from the outside is of a continuous body. FIG. 5 illustrates An alternative to this preferred arrangement wherein the outer shape includes a step feature. Other alternatives are also possible.

[0075] With reference to FIGS. 2 and 3, the ducting 4 extends downwardly to an opening (the first outlet) from the chamber into the reservoir. As the reservoir means is adapted to receive and contain liquid such as soft drink or water or the like and this is to be dispensed from this reservoir via the at least one ducting 4, the ducting 4 extends from a first outlet 12 into the reservoir means to a first liquid inlet 13, which is preferably proximate to the lower most regions of the reservoir means. This will ensure that substantially all of the liquid contained in the reservoir means can be drawn through the ducting 4.

[0076] The chamber is sealed and preferably air tight save for the openings provided by the at least one first liquid outlet into the chamber and an the at least one second outlet 14.

[0077] The chamber may be provided with a lid provision 7 which can be sealingly engaged to the upper mouth region 8 of the chamber. Alternatively processes may be utilized in the manufacturing of the present invention wherein this chamber is of a one piece member as for example as shown in FIG. 5. Where a lid is provided, this lid must securely and sealingly engage with the chamber. This may for example be achieved by a tapered mouth region 8 engagable with a complementary tapered mouth engagable portion of the lid 7. Further features such as annular ribs or a treaded type of engagement may also be provided for this purpose.

[0078] The apparatus is preferably of a nature where the reservoir has a chamber engagable mouth regions, such that when it is engaged with the chamber the mouth region of the reservoir is substantially scaled therewith the preferred cylindrical shape of the reservoir and the chamber means the apparatus preferably has the overall shape of a tall glass with a lid or a can of soft drink or the like.

[0079] In operation of the novel drinks container as for example shown in FIG. 4, a person can provide suction to the second outlet by placing this to the mouth of the user.

[0080] As the reservoir means preferably has at least one pressure equalizing aperture 9 or other opening or the like to allow for air to be displaced into the reservoir means, liquid can be displaced from the reservoir through the ducting 4 and into the chamber as an unsupported column or unducted flow of liquid.

[0081] Upon the application of suction to the second outlet (whether directly by the user or indirectly via other chambers or the like) the only way in which pressure in the chamber can move towards equalization is for liquid to be drawn through the ducting 4 to move and upwardly, and out through second outlet.

[0082] Liquid momentum being drawn up through the ducting 4 is preferably directed towards the upper opening of the chamber and thereby exits the chamber without substantially flowing astray from bring an unsupported column between the openings of the chamber.

[0083] The fact that the chamber is substantially sealed to any other flow of fluid ensures that a maximum suction pressure is transferred to the ducting 4 to draw the liquid of the reservoir means upwardly therethrough.

[0084]FIG. 5 illustrates that the present invention can be provided wherein a non-vertical alignment of the two openings of the chamber occur. Likewise the container of FIG. 4 can be utilized on an angle wherein the aligned ductings are not.

[0085]FIG. 6 illustrates an arrangement wherein a single lower ducting 4 and preferably also single upper 15 ducting can be provided with diversions/contractions which extend/reduce to provide a plurality of openings in the upper and lower parts of the chamber. A manifold type arrangement or similar may perhaps be used in this respect. Alternatively a plurality of ductings to provide such effect may be provided as for example shown in FIG. 8. Indeed in FIG. 8 there is shown an illustration where there are two lower ductings 4 converging the flow of fluid therefrom into the chamber to a single upper opening, (second inlet opening).

[0086] To reduce spillage of any flow of the unsupported column of water in the chamber, the most preferred form of the present invention incorporates a smaller opening of the lower ducting into the chamber than the opening from which the upper ducting preferably extends from the upper or second inlet opening of the chamber.

[0087] In FIGS. 4, 6, 8 and 10 the pressure equalization means of the reservoir means is preferably an opening directly into the reservoir means from external of the container. Such an opening may preferably be provided in the wall of the reservoir means or may be provided as a gap between the junction of the upper and reservoir means in the forms of the invention shown in FIG. 5. Such may be achieved by an imperfect sealing between the upper and lower members providing the upper and reservoir means. Where a flexible liquid reservoir is used, such pressure equalization means way not be necessary.

[0088] In an alternative form as shown in FIG. 11 the equalization means 9 may be a ducting which extends from an opening in the junction 5 between the chamber and reservoir to an opening in the chamber. As shown in FIG. 11 this opening in this chamber is on the lid 7 but may alternatively be through any other wall section of this compartment not extending back into this reservoir means.

[0089] In an alternative the apparatus 1 is of a single container which is separated into at least two compartments 2, 3 by a division providing means 5, as shown in FIG. 10.

[0090] The apparatus shown in FIG. 12 does not have a, or significant upper duct. The chamber may be provided with merely an outlet (second outlet) to which the mouth of a user can be placed to provide suction. This version of the invention shows that the ducting between the first inlets and first outlets need not place the first outlets at the junction between the reservoir and the chamber.

[0091] The flow of liquid from the ducting 4 is preferably of a momentum which has sufficient speed to reach the second inlet or chamber upper opening, and is preferably also of a direction, directed at the second inlet/opening. At least in one broad sense of this aspect, it is preferably at least that portion of the ducting immediately before the first outlet which is vectored in the direction of the second inlet/opening. Preferably the portion of the ducting immediately extending from the second inlet may also be of the same vectoring as other duct.

[0092] In a further embodiment of the present invention, and as shown in FIG. 16, the drinking apparatus in a form which results in the formation of a downward stream of water or a waterfall between the first liquid outlet and the second liquid inlet. In this configuration, a stream of water is generated between the first liquid outlet and second liquid inlet and flows substantially unsupported. In this form, the flow of fluid exiting from the first liquid outlet is in a direction towards the second liquid inlet such that the unsupported column of water created by sucking on the second liquid outlet causes that unsupported column of water to be substantially entirely directed to the second liquid inlet for ducting between the second liquid inlet and the second liquid outlet.

[0093] An example of the ducting arrangement is for example as shown in FIG. 16 however the ducting may be of a completely different nature and may include a substantial portion of the first ducting 4, being outside of the chambers. Configurations of ducting to provide the waterfall version of the present invention may include the variations of ducting as shown in FIGS. 5, 6, 8 or other forms.

[0094] With reference to FIG. 17, a further alternative or additional feature of the present invention is disclosed. In FIG. 17 there are shown electrical contact points 38 which are part of an electronic circuit, the circuit being completed upon the flow of unducted water through the drinking apparatus of the present invention. The contact point 38 are preferably located so as to impinge into the flow of water upon the use of the drinking apparatus of the present invention and thereby to complete a circuit which preferably actuates electronic means such as lights and/or sound generation means.

[0095] With reference to FIG. 17, the contact points are shown to be provided proximate to the first liquid outlet. It is envisaged however that tho electrical contact points could be provided at the first liquid outlet or at the first liquid inlet or for that matter anywhere along the ducting between the liquid outlets and liquid inlets. However with the provision of the electrical contact points within the compartment 3 where the inducted flow of water is generated, the contact points can be provided in a manner such that when no liquid is flowing, there is no chance of any residue liquid from closing the circuit and actuating the electronic devices such as the lights or sound providing means. Although the electrical contact points could be provided at the first liquid outlet or second liquid inlet, resident liquid (after the flow of liquid has stopped) which may adhere to the surfaces at the liquid outlet or inlet, may still cause for the circuit to be closed across the electrical contact points. Accordingly in the most preferred form the electrical contact points are provided separated and insulated from the liquid outlet or inlet or the ducting between the liquid outlets and inlets and are provided in a region within the compartment 3 where once the unducted flow of liquid is generated they provide the closing of the circuit to actuate the electronic means.
